本文主要是以古典殼理論為基礎,根據不同的假設所對應的四種殼理論(Love, Flügge, Donnell, Sanders 理論),進行正交性複合圓柱層殼受溫度作用下之挫曲分析。
在推導各種古典理論基本方程式的過程中,除了本身各理論上的假設外,還依據材料特性和物理性質作了簡化公式的假設。為了使求解程序具較佳之效率,代入了適當之無因次化場量變數參數;本文將理論推導出的控制方程以位移場表示,利用求解特徵值的方式,求解各式不同的古典殼理論之複合圓柱層殼臨界挫曲溫度,並計算在此臨界溫度作用下,殼之模態應力與應變場,並進行綜合相互比較。
數值範例上,本文針對各種不同正交疊層排列情形,分析圓柱層殼挫曲行為。參數分析中則改變幾何參數,求解層殼受溫度下的挫曲應變與挫曲應力,並討論各理論的差異作評估比較。
